Hmm, while i was writing this, i was thinking of all the movies
and books and threads that shows a girl sticking through with a
guy, even though the guy did many wrong things to the girl, but the
girl stuck on and eventually they got married and lived happily
ever after.
If the girls can do it, why not the guys?
And there are some people who, either through their sixth sense, or
know for a fact that This current gf/bf is "The One", and have
expanded and showered all their love on them.
Personally, i think it would be a waste to just give up, she's
young and weak, and if its his friend who started it, i don't think
the entire blame should fall on her. By saying this i was thinking
of the scenario when Satan gave the apple to Eve.
But then again, every situation is unique, especially when feelings
are involved, and i don't think we should stereotype. I'm rambling
again... Hope i answered your question though.
